Huawei H12-831_V1.0 Exam With Confidence Using Practice Dumps

Link-LSA (ID 0.0.0.4):This LSA is originated by each router to describe its link-local IPv6 address and prefixes.The value 0.0.0.4 maps to the interface on R1, which has Router ID 10.0.1.1.✅ So the origin router is 10.0.1.1.

Network-LSA (ID 0.0.0.5):This LSA is generated by the DR on the link. In the diagram, R4 (10.0.4.4) is connected to the shared network (GE0/0/1).✅ So the origin router is 10.0.4.4.

Inter-Area-Prefix-LSA (ID 0.0.0.1):This LSA is used to describe routes from other areas and is generated by an ABR.In this case, R3 (Router ID 10.0.3.3) acts as the ABR.✅ So the origin router is 10.0.3.3.

Intra-Area-Prefix-LSA (ID 0.0.0.2):This references a Network-LSA, and the reference type is 1 (Network-LSA).Since the Network-LSA (0.0.0.5) came from 10.0.4.4, this also must have been generated by R4.✅ So the origin router is 10.0.4.4.

✅ Final Answer Summary:

Number

Origin Router

1

10.0.1.1

2

10.0.4.4

3

10.0.3.3

4

10.0.4.4

Official Huawei Extract:

" Each router in OSPFv3 generates Link-LSAs for each interface. The DR generates Network-LSAs. ABRs generate Inter-Area LSAs, and the Intra-Area-Prefix LSA references either Router or Network LSAs depending on the link type. "

— [Huawei HCIA-Datacom OSPFv3 LSAs Section]

Huawei VRP requires MPLS and the Label Distribution Protocol (LDP) to be enabled at both the global and interface levels before dynamic label-switched paths can be established over an interface.

First, the mpls command enables the global MPLS function. Next, mpls ldp enables the global LDP process. These commands establish the necessary control-plane functionality.

At the interface level, mpls enables MPLS processing on GE0/0/1, and mpls ldp enables LDP neighbor discovery and label distribution through that interface.

All four commands are necessary in the configuration sequence shown in Huawei ' s training material. In a complete deployment, the administrator must also configure an appropriate MPLS LSR ID and ensure IP connectivity between neighboring devices.

Therefore, all four options are correct.
